"When the pores of the air are already loaded with water vapor, it is very little use to hang the clothes out. They will not dry. The air cannot take in any more water, because its pores are already full. No evaporation can go on. The water remains in the clothes."SUMMARY
Steam is water in another form. The heat breaks up the water into tiny particles lighter than the air. They rise and ?oat away in the air. The air absorbs them into its pores. Vapor is something like steam. Some amount of vapor rises even in cold weather. Dry air can evaporate and absorb more moisture than damp air.
